Smell, or olfaction, is a chemoreception that forms the sense of smell. Olfaction has many purposes, such as the detection of hazards, pheromones, and food. It integrates with other senses to form the sense of flavor. [8] Olfaction occurs when odorants bind to specific sites on olfactory receptors located in the nasal cavity. [9]
Special somatic afferent fibers (SSA) are the afferent nerve fibers that carry information from the special senses of vision, hearing and balance. The cranial nerves containing SSA fibers are the optic nerve (CN II) and the vestibulocochlear nerve (CN VIII).
Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them. [ 1 ] The receptive field is the area of the body or environment to which a receptor organ and receptor cells respond.
Gyanendriya is the organ of perception, the faculty of perceiving through the senses. The first five of the seventeen elements of the subtle body are the "organs of perception" or "sense organs". [2] According to Hinduism and Vaishnavism there are five gyanendriya or "sense organs" – ears, skin, eyes, tongue and nose. [2]
The olfactory bulb is a special structure that processes olfactory sensory signals and sends its output to the olfactory part of the pallium. It is a major brain component in many vertebrates, but is greatly reduced in humans and other primates (whose senses are dominated by information acquired by sight rather than smell). [48]
Sensory organs are organs that sense and transduce stimuli. Humans have various sensory organs (i.e. eyes, ears, skin, nose, and mouth) that correspond to a respective visual system (sense of vision), auditory system (sense of hearing), somatosensory system (sense of touch), olfactory system (sense of smell), and gustatory system (sense of taste).
The term originally entered English from the Late Latin in the mid-17th century, from the stem sens-("sense"). In earlier use it referred, in a broader sense, to the brain as the mind's organ (Oxford English Dictionary 1989). In medical, psychological, and physiological discourse it has come to refer to the total character of the unique and ...
Special visceral afferent fibers (SVA) are afferent fibers that develop in association with the gastrointestinal tract. [1] They carry the special sense of taste (gustation). The cranial nerves containing SVA fibers are the facial nerve (VII), the glossopharyngeal nerve (IX), and the vagus nerve (X). [ 2 ]
